Well, thanks for asking, as far as my opinion, look OK to me as pictured. If they were,.doubt it would have a material bearing on their value. Most uncovered, detector finds are cleaned and
enhanced, if these two were.
As the one most desirable, I like both; the first is from the
Rome mint and second from the city of Amiens, (I see MB with branch with A off
flan),
Magnentius home town and more secure city during
his cival war with
Constantius II in the closing months of the losing struggle.
If I were to choose, probably the latter because of the
mint. An example on Woodwinds
